Hello Jose,
yes, the firmware needs some additional features, but we can start to brainstorm.
Currently the functionality is somewhat improved, even easier than the BLE-Shield v1.0.0 firmware to use.
There is still no Library and it will not in the future

Well one feature would be to use the BGLib provided by Jeff Rowberg instead of the firmware I created.
This would give you the chance to interact as you want with the Shield, but make a Library necessary.
It would be good if we could brainstorm a little bit.
Peripheral and central role would be great to support

Cheers,
Michael.
